T0 at w7wm it may concern.-

Be it known that 1, CHARLES ZIMMERMAN, a citizen of the United States,residing at Araby, Frederick county, State of Maryland, have inventedcertain new and useful Improvements in Shutter-Bowers and Fasteners, ofwhich the following is a specification.

My invention relates to shutter bowers and fasteners, and has for itsobject to improve and simplify the construction of such articles and toprovide such a construction as will avoid the objections to thoseheretofore made; and to these ends my invention consists in the variousfeatures of construction and arrangement of'parts adapted to operatesubstantially as hereinafter more particularly set forth. 1 1

Referring to the accompanying drawings, Figure 1' is a perspective Viewof a window shutter and sill, showing the shutter bower and fastener inposition, the shutter being held and locked open. Fig. 2 is an enlargedperspective view of the shutter portion of the locking device orfastener. Fig. 2fis a detail of a modification. Fig. 3 is a side view ofthe same attached to the shutter. Fig. 4 is a detailed View of a portionof the bracerod, showing one arrangement of notches. Figs. 5 6, 7, and 8are side views, partly in section, showing the parts in variouspositions; and Fig. 9 isa side view, partly in section, showing amodification in the construction'of the locking, device. 7 r

My present invention relates generally to that class of shutter bowersand fasteners disclosed in my prior patents Nos. 537,334, of April 9,1895, and 564,548, of July 21, 1896, and embodies improvements in thedetails of construction and arrangement of parts, providing an improvedmode of operation whereby some of the difficulties and objectionsarising in the use of the devices shown in my prior patents areovercome.

Referring to the accompanying drawings, S represents a shutter, and T aportion of the sill of a window to which the shutter bower and fastenerare attached and are adapted to operate, broadly speaking, in awell-known way. Mounted in the sill is a sill-plate 0, provided with anumber of openings 0, one of which is shown elongated, and the side'ofthe sill-plate is inclined, as at c. This sill-plate in the sill-plateC, and itwill be understood that the position of the shutter could beadjusted by adjusting the brace-rod in difierent positions in thesill-plate.

Attached to the shutter is a bracket D, which is of the usualconstruction, and connected to the bracket is the brace-rod A, it beingprovided with a bent end adapted to codperate with the sill-plate andsocket E for holding the shutter in the desired .opeu position'in theusual way.

B represents the lock piece or portion of the locking device which isadapted to be attached to the shutter, and my improvements are moreespecially directed to the details of construction of thispart of thedevice, although it also includes other parts, as will be pointed outhereinafter. I call it for convenience, may be of various forms, but ispurposely shown as conforming in general design to the lock of myprevious patents, but it differs therefrom essentially in details ofconstruction, which produce a difierent mode of operation of the device.This lock comprises, broadly speaking, abase-piece B, anupwardly-projecting pullpiece B and a forward extension B which isrigidly connected with the base-piece and is preferably formed integraltherewith, although it may be separately made, as indicated in Fig. 9.In my prior constructions this extension B was pivoted to the baseportion and served in itself as a locking-piece to directly engage andlock with the sill-plate; but in the present construction the lock orlocking-pieceB does not in itself on gage with the sill-plate, but itserves as a carrier and support for the brace-rod A, the bent end ofwhich cooperates with the lockB and engages the sill-plate C, and thelocking device proper includes the lock-piece B, the bracerod A, and thesill-plate O. This lock-piece B is peculiarly constructed and isprovided with a lug or projection b on its outermost portion whichextends upward and inward,

This lock, as

ISO

forming, in effect, a hook and having a relatively sharp edge on itsinnermost extension. The lock-piece is also provided with a rest portionor receptacle d, and between this rest portion and the lug is an opening6. .At the inner portion of the rest or receptacle there is a shoulderf, and all these parts and specific constructions are important in theperfection of my invention. While this lock may be used with thebrace-rod A of the usual construction, in order to secure all theadvantages of my invention the bent end of the brace rod is providedwith one or more notches a, on one side of the bent end, or, as shown,the notches may extend on more than one side, although the principaladvantages arisingfrom this construction can be obtained by using thenotches on one side only, as will appear hereinafter.

Such being the general construction of my improvements, the advantagesthereof will be largely understood by those skilled in the artfbut maybe more thoroughly appreciated in describing the ordinary operation ofclosing and locking the shutter. We assume that the parts are in theposition shown in Fig. 1, and when it is desired to close the shutterthe brace-rod is removed from the sill-plate and placed on the lock B,and then the shutter is closed in any desired way, as by means of thefinger-pull B or by taking hold of the shutter itself or otherwise, andthe shutter is usually slammed shut, and of course it is desirable thatit shall be automatically locked in the operation. The bent end of thebrace-rod may be placed in the opening a of the lock, or it may beplaced upon the rest or receptacle d, as shown in Fig. 5, and when inthe latter position the shoulder fwill prevent the rod sliding towardthe shutter, and the momentum given to it in closing the shutter Willthrow it across the hole 6 and its end will strike the lug b, as shownin Fig. 6, and the end of the lug impinging upon one of the notches a ofthe brace will prevent its flying out of engagement withthe lock, and itwill eventually drop into and through the hole e into one of theopenings 0 of the sill-plate O and the parts will become looked, asshown in Fig. 7. If perchauce in closing the shutter the bent end of thebrace-rod A is placed in the hole e of the lock-piece B on the shutterbefore closing, when the shutter is closed the end of the brace-rod willimpinge upon the inclined portion 0 of the sill-plate O, as shown inFig. 8, and this will tend to lift the end of the brace-rod and isliable to throw it out of engagement with the lock B; but the projectionb in my improved device will eugage one of the notches a on the end ofthe rod and prevent its flying out, and when the shutter is completelyclosed the brace-rod will fall downward by gravity into one of theopenings c of the sill-plate O, as shown in Fig. 7. The bracket D towhich the brace-rod is pivoted will prevent the rod from twisting whenits free end engages the projection 17, so that a firm and effectivepull can be applied to the shutter for closing it.

When the shutter is closed from the inside, if the brace-rod is placedinthe hole 6 the rod may be used to pull the shutter closed, and in thuspulling the shutter the bent end of the rod a is liable to be pulled outof position; but the projecting end of the lug will engage one of thenotches in the brace-rod and prevent this taking place. So, too, ifperchauce there is a downward pull on the brace-rod which would preventits being elevated when it is used to close the shutter the end of therod would impinge upon the inclined portion 0' of the sill-plate and isliable to be thrown out of the hole 6; but the projecting end of the lugwill engage one of the notches in the rod and prevent this happening,and when the rod is released it will fall into the opening in thesill-plate and the parts will be securely locked together. So, too, theadvantages of my improved construction are very apparent if perchaucethe shutter is closed from the outside and the brace-rod is supportedeither on the rest portion of the lock or in the opening therein, andwhen the shutter is pushed to close the same the brace-rod is liable tofly out and become disengaged" from the look; but the projecting end ofthe lock will prevent this and-insure the bent end of the brace-roddropping into the openingin the sill-plate, so that the parts will beautomatically locked.

It is apparent that some of the advantages thus stated will follow theuse of a brace-rod of the usual construction-that is, without thenotches a; but it is not as eifective and certain in its operation aswhen the rod is provided with the notches. While the lug is preferably asingle lug, it is manifest that it may be divided in the middle, asindicated in Fig. 2, making a two-part lug or practically two lugs, or,as indicated in Fig. 2*, it may have two extensions, being, in effect,two lugs, one being higher than the other, so that one of them will bearupon the body of the brace-rod while the other engages the downwardprojecting portion of the bracerod.

While the features of novelty herein set forth are comparatively simplewhen considered in the abstract, in practice they are of greatimportance in tending to produce a perfectly-operating shutter-bower ofthe character described, and the features of construction involveimproved functions and improvements in the operation of the device.Thus, for instance, the notches in the rod oo- IIO operating with thelug having the inwardly- 1.
